Full Version: V4 beta Aug-28-2018 available now

Show messages:  1-3  4-23  24-43  44-63  64-65

Hi Alex, thanks for sending the files. I tested opening the V4 STEP file in Rhino, ViaCAD, Autodesk online viewer, and back into MoI and the names come through ok in all those cases.

I see in a discussion on the SolidWorks forum from last year where you were asking about a similar problem, another user mentioned to try unchecking the "enable 3D interconnect" option in SolidWorks, does that make any difference?

I have sent a message to the author of the STEP import/export library that MoI uses to ask what has changed in STEP export with the newer library that is used in v4 (the June v4 beta updated these libraries from v1.7.11 to v2.0.8) and if there is any way to configure the export to get SolidWorks to see the name.

Thanks, - Michael

Hi Michael,

I have checked with SW Interconnect function and when I switch to this mode where it keeps the step file as a reference file which you can re edit whether it comes out of MoiV3 or MoiV4 the parts names are lost - will do some more research on this I use this heavily in my work flow - I use MOI as a concept tool and general shaping do final preparation in SW then save as STEP for sharing with other SW users.

Hi Alex, can you please contact me by e-mail at moi@moi3d.com and we can continue there?

The author of the STEP import/export library wants to send some test files over to you to see if this can be tuned up.

Thanks, - Michael

Hi, I just wanted to report that in version 4 is not remembered the last directory all the times that I have to open a file I have to redo the path through the various directories, only if a file is saved in .3dm Moi format v4 remembers the last route used, with Version 3 this does not happen. Of course I must also say that I use Moi3D with Wine.

---

Hi pafurijaz, thank you for reporting the file open directory problem.

It seems like that may be a bug in Wine since normally on Windows the file dialog system code does the job of remembering the last used directory. It should not be difficult to make MoI do that itself when running on Wine though, I will look into that.

Hi!

Just a quick update concerning MoIV4 on Linux/wine, the object selection issue (as discussed earlier at http://moi3d.com/forum/messages.php?webtag=MOI&msg=8839.1) still exists for nvidia cards. I tested on Fedora 28 with nvidia driver 396.45.

best regards

Hi Michael,

I just noticed something and don't know if this is related to the MoI V4 beta or not, but as I've only installed the latest beta I thought to post it in this thread.

When I use the copy PDF to clipboard function (Top view, Fit to page), then paste it into Affinity Designer, the orientation of the pasted layer is tilted. You can see it in this combined screenshot:

Hi Metin, hmm that's interesting. I'm not aware of anything that MoI is setting in the PDF to make that happen, I'd think it's likely something that would need to be fixed in Affinity Designer.

I just tried it over here using MoI v4 and Affinity Designer v1.5.0.36 (on Windows) and I don't see that happening:



Do you have any other programs that can put a PDF on the clipboard to see what happens with them?

Hi Michael,

Indeed, when you copy a native MoI rectangle to the PDF clipboard, all is fine, but try the one in the attached MoI file.

A parent layer is automatically created in Affinity Designer, but you'll have to select the child layer (the actual shape).

The rectangle in the attached MoI file was created by:

1: Unwrapping Isocurves from a solid using UnwrapCurve.
2: Using Sweep to create a surface from the unwrapped U and V curves.
3: Selecting the edges of the surface and using Join to create a new closed rectangle.

Hi Metin, thanks for posting the file. The difference with your rectangle there versus a newly drawn one is that 2 of the sides in that new one are cubic spline curves made up of 4 control points instead of just basic 2 point lines. Maybe that information will help the Affinity developers figure out what is causing that behavior in Affinity Designer.

Over here I still can't repeat that with your new file, I get this result - does this have the right thing selected in Affinity? Also do you get the same behavior if you save to a PDF file and use Place to insert it in Affinity instead of using the clipboard?

Hi Metin, I updated Affinity Designer to version 1.6.5.123 and I can now reproduce the rotated frame behavior when pasting into Affinity. It didn't happen in Affinity Designer version 1.5.0.36, so it looks like a regression in Affinity. I'd recommend sending a bug report to them describing the problem.

It may actually be a new feature though, the start point of the rectangle in the file you attached is in the bottom right corner and I guess they are using a line between the object centroid and its starting point as the initial rotation.

As far as I can see there isn't anything I can do in MoI to control that initial edit frame rotation in Affinity.

Hi Michael,

Many thanks for checking it out. I'll file a report at the Affinity Designer forum.

Names are lost when moving a file from MoI in Step format to Fusion as well.

Hi Michael,

Just wondering if it would be possible to add the function when opening other file types in MOI to keep the filename referenced as per opening a 3dm file. For example here is a typical job folder in which I use the STP file as a crossover to SOLIDWORKS from solidworks create individual parts which are then exported as DXFs for laser cutting manufacture. I sometimes need to add notes to the DXFs files rather than import and save as could these file be handled as native 3dm files.




thanks
Alex.

Hi Alex, so the reason why the current file name isn't set when you open something other than a .3dm file is that only .3dm files can contain everything that you create in MoI.

So for example if you open a .dxf file and then add a background image, if MoI set the current file name to that .dxf file and tried to save out to that same .dxf file when you closed MoI, it would appear to the user as if their background image was saved while in fact it was not.

But are you asking for MoI to save to a .3dm file in that situation and not the original opened file type? That seems like a little unusual file handling behavior to me but it could be possible to make an option to do that I think.

Hi Michael,

Here is a more clear example I have opened a DXF in MOI ( My default DXF Viewer) but when opened no reference to actual file is kept.





You can see when there are more parts to view the names can get lost if not referenced.

Hi Alex,

re:

> but when opened no reference to actual file is kept.

Yes, that's how it is intended to work. The reason why is because MoI will write to the current active file name when you use the Save command or when you exit MoI and choose "Save changes". But MoI is only able to save a subset of its possible information to a .dxf file so if you were to make something that MoI does not write to .dxf files you could end up thinking you had saved your complete work while actually only a subset was saved to the .dxf file.

To avoid that data loss scenario, MoI will only set the current file name when you open a .3dm file since that's the file format that MoI can store all of its information into.

Hi Michael,

Thanks for letting me know - in rhino if you import a file in a blank document it names that current file the import name then go save as it still keeps the filename as the first preference would at least this be possible?





thanks
Alex.
